World's biggest sperm bank, Cryos, tells redheads: We don't want your semen

"There are too many redheads in relation to demand," Ole Schou, the director of Cryos, told the Danish newspaper, Ekstrabladet, according to London's Telegraph.

Men with scarlett manes sell "like hot cakes" in Ireland, Schou said, but that's about it.

"I do not think you choose a redhead, unless the partner - for example, the sterile male - has red hair, or because the lone woman has a preference for redheads," he said, the Telegraph reported. "And that's perhaps not so many, especially in the latter case."
